graph of skin cancer
Graph of skin cancer. I located a government website with a articles on skin cancer and graph of skin cancer for different groups of people.
There is a graph of skin cancer for Caucasian Males and a graph of skin cancer labled Cancer Incidence - Caucasian Females. For African-American Males and females here is no graph of skin cancer neither melanoma or others types of skin cancer. I take that since the is no graph of skin cancer for african americans they must noy get skin cancer. Is this true? How about Asians. Here is the link to the graph of skin cancer site.

Get Sun-Kissed, Not Sunburned
Get Sun-Kissed, Not Sunburned
The sun doesn't have to wreak havoc on your skin this summer, says DeeAnna Glaser, M.D., professor of dermatology at Saint Louis University School of Medicine. She offers tips and her favorite ways to look tan without risking skin cancer or melanoma.
Newswise — Saint Louis University Dermatologist Offers Advice, Picks for Hot New Sunless Tanners
Hot, humid and hazy. Yes, it’s summer again, and time for the sun to wreak havoc on your skin.
Not so fast, says dermatologist DeeAnna Glaser, M.D., professor of dermatology at Saint Louis University School of Medicine. There are some simple guidelines to keep in mind before heading out to the ballpark, the pool and even the grocery store this summer.
Everyone is at Risk for a Bad Sunburn
“Although fair-skinned people are far more likely to get a sunburn, even people with darker skin can burn and get skin cancer,” Glaser says. “Young skin is also more susceptible to sunburn, and much of our skin’s sun damage occurs during our childhood and teenage years, so parents should put forth every effort to protect their kids from the sun.”
Not only are sunburns the “number-one cause” of wrinkles and aged-appearing skin, says Glaser, but they also increase one’s chances for skin cancer dramatically.
Not all Sunscreens are Created Equal
“Protect your skin by applying lots of sunscreen 15 minutes before going out in the sun and reapply every two hours and after swimming,” she says. “The sun’s rays are reflected by water, sand and sidewalk, so even if you’re in the shade, you should still apply it.”
Sunscreen with a sun protection factor (SPF) of at least 15 is necessary. Look for bottles – and sunglasses – with both UVA and UVB protection; UVA rays penetrate through window glass, says Glaser, and although they don’t cause sunburn, they penetrate deeper into the skin and can lead to skin cancer, melanoma, wrinkles and skin discoloration.
Sunscreen has improved greatly over the years, Glaser says.
“I think it’s great to be able to incorporate sunscreen into other products that you are already using, like moisturizers and makeup,” Glaser says. “There are also many different formulations today for sunscreens like gels, sprays and quick-absorbing creams to avoid that ‘greasy’ feeling of normal sunscreens.”
Glaser notes that many of her male patients opt for gel-based sunscreens, and she recommends a “physical sunblock” that contains zinc oxide (such as Vanicream and Blue Lizard) rather than a chemical sunscreen because it gives broad-spectrum sun protection and is less irritating than traditional sunblock.
Dress to Protect
In addition to sunscreen, Glaser also advises that people wear wide-brimmed hats when outside – “at least four inches all the way around. Baseball caps don’t count!” she says.
The sun’s rays are the strongest between 10 a.m. and 2 p.m., and Glaser suggests during that time wearing solid clothing, and, while they may not be entirely comfortable in the middle of July, darker-colored long-sleeved shirts and pants.
Go Ahead – Fake It
“Many of the tan Hollywood stars that you see on TV are in movies now and actually tan from self-tanners and airbrushed tans,” Glaser says.
Glaser points out the new Jergens Natural Glow Daily Moisturizer, which comes in varieties for both the face and the body.
“It’s more forgiving and adds color to the skin gradually after several applications,” she explains. “In general, self-tanners work by coloring the surface layer of the skin and last for about two weeks – until the skin cells naturally shed.”
Spray-on tans, such as Mystic Tan, have become increasingly popular among men and women, especially before special events, the dermatologist says.
Dr. Glaser also recommends bronzers, which are applied like makeup to places the sun would normally hit, like the cheeks, forehead and the nose.
Saint Louis University Medical Center offers the widest range of health professions schools among U.S. Catholic medical centers. In addition to having the first School of Medicine west of the Mississippi River, the Saint Louis University Medical Center includes the Doisy School of Health Sciences, the Center for Advanced Dental Education, the School of Public Health and the Center for Health Care Ethics.

Skin Cancer Sunburn DNA Test
Genesis Genomics is Offering Something New Under the Sun
New technology developed by a North-East company could help give sun worshippers some peace of mind. Graeme King spoke to founder Professor Mark Birch-Machin.
Projecting your skin in the sun has up to now been a matter of common sense, lashings of sun cream, and careful examination of any moles on your body. But now an North-East academic is bringing science to bear on the matter with a test which can identify how much your DNA has been damaged by the sun, and ( allied with a lifestyle questionnaire ( the provision of tailored advice to keep you safe both from sunburn, and skin cancer.
Professor Mark Birch-Machin is the man behind Genesis Genomics, formed at Newcastle University to commercialise his academic work.
The professor's team has been looking not only at developing the "skinphysical" DNA test, but also to develop a rating system for sun creams, to grade them according to how well they protect your DNA.
It is this development which has interested cosmetic companies and will see Prof Birch-Machin shortly sign a deal to work in partnership with a major company, and pave the way for Genesis to attract new investment. Prof Birch-Machin said: "We can help cosmetic companies to design smart sunscreen, and we can test existing sunscreens on their ability to prevent DNA damage.
"What we will be able to provide is, ultimately, a DNA protection factor for sunscreens. We are talking to quite large cosmetic companies. They have come to us saying they would like to access our technology. We expect to sign something very soon."
Prof Birch-Machin said Genesis Genomics's new chairman Jim Skinner, who has experience of taking more than 100 products through the regulatory hurdles of the FDA (Food and Drug Administration) in the US, was helping to lead the process of commercialising the company's technology.
Genesis now has a revamped business plan, with the idea that companies it signs up to work with will appear on it. Prof Birch- Machin said: "We will take that plan to investors both in the North- East and in north America. Now is the time to invest."
The more immediate use of Genesis's technology is the skinphysical test, however, which allows individuals to check the state of their skin, and hence how careful they need to be in the sun.
Prof Birch-Machin said: "We have developed what you can summarise as sunburn DNA technology. We are number one in the world for doing this.
"We want people to enjoy the sun, but enjoy it more safely. We are careful to say we are not offering cancer diagnosis ( this is about a measure of sun damage.
"So it's about a level of risk, rather than a diagnosis.
"We just try to get them to adhere to the Sunsmart Code (safe sun exposure advice promoted by Cancer Research UK)."
Genesis asks those wanting a skinphysical test to fill in a lifestyle questionnaire, then this information is combined with the results of tests on a small skin sample, taken from the end of the elbow crease on the upper arm ( to check how an individual's DNA has been damaged by the sun.
Currently, the test is only available from a small number of private cosmetic dermatology clinics but Genesis is also talking to other potential outlets.
It costs from pounds 250, but Genesis hope to reduce the price as more and more tests are performed and the company can benefit from economies of scale.
Skinphysical is also aiming to develop a system to telling people the age of their skin ( to show results such as a 30-year-old woman having the skin of a 50-year-old in terms of damage.
Genesis, with 15 staff, is currently renting space within the dermatology department at Newcastle University, but expects to move in August to new facilities in the university's medical school, which have been refurbished by CELS (Centre of Excellence in Life Sciences).

Skin Cancer Effective Sunscreen
How to choose an effective sunscreen
Updated: 2006-06-26 14:30
Going in the sun to sun oneself is fraught with a myriad of risks. Besides sunburn one has to keep in mind the fact that the ultraviolet rays of the sun have the ability to cause skin cancer. Some believe the sun causes skin cancer.
Given such a scenario, it is imperative that the correct methods are used to protect your skin from the sun. It is here that the user needs to be cautious and choose wisely from the wide array of products that dominate the market. Tall claims made by sunscreen manufacturers are best taken with a pinch of salt. Recently the manufacturers were under the cosh because they made false claims on the labels.
The July issue of Mayo Clinic Women's HealthSource contains some useful tips on how to go about choosing the right sunscreen for your skin. The report says that an average adult requires 1 ounce of sunscreen that is equivalent to 2 tablespoons, for covering the whole body.
The first thing to look for in a sunscreen is protection from ultraviolet A (UVA) and ultraviolet B (UVB) sunrays. Both are equally harmful. Secondly a sun protection factor (SPF) of 15 is the bare minimum that deflects about 93 percent of the UVB rays. It also enables you to remain in the sun for a longer time.
The third factor to note is the water resistant and water proof qualities. This is vital if you sweat a lot or are planning to swim. "Water-resistant sunscreen protects for 40 minutes; waterproof sunscreen for up to 80 minutes," the report says, reports Earthtimes.
According to BusinessWeek, even the best sunscreens wear off, so reapply them every couple of hours, especially if you've been sweating or swimming. And know when you've had enough. A good way to keep track of your cumulative exposure is to get one of the new products that react to UV light. SunSignals self-adhesive patches, $5 for a pack of 18, gradually change color to a bright orange when exposed to UV rays, warning you to reapply your sunscreen or go inside.
A better bet is an electronic UV monitor, which costs about $25 or $30. La Crosse Technology makes one that looks like a sports watch, or there are styles you can wear around your neck from Chaney Instrument and Oregon Scientific. Program them with your skin type, from fair to dark, and the SPF of your sunscreen. They calculate the strength of the days's UV rays and use that to count down the time you can stay outside safely. Oregon Scientific's model is splash-proof and includes a digital thermometer.
Jason Rivers, a dermatology professor at UBC, however, says that the benefits of sunscreen far outweigh any possible risks.
As many as 20 percent of Canadians have an "irritant reaction" to sunscreen, Rivers told the Straight, and fewer are actually allergic. A common allergen in commercial sunscreens is the chemical benzophenone, he said, which also goes by the names phenyl ketone, diphenyl ketone, or benzoylbenzene. Although it isn¡¯t clear how much of benzophenone is absorbed into the bloodstream, the substance has been found in urine samples of study participants. Nevertheless, he maintains that sunscreens are safe.
"There's no evidence these ingredients cause changes to cells or are carcinogenic in their own right," said Rivers, who's also a spokesperson for the Canadian Dermatology Association. "There's no evidence they have a negative effect on vitamin-D metabolism. There is evidence to support they prevent sunburn and reduce premature aging of the skin and the risk of certain cancers," reports Georgia Straight .

Skin Cancer and Sunscreen Labels Questioning
Sunscreen labels need policing
By Times editorial
Published June 20, 2006
Sunscreen labels. For seven years total the Food and Drug Administration has known that many sunscreen labels mislead consumers into thinking they are being fully protected against cancer-causing sun rays. And while skin cancer cases continue to increase, the FDA's lack of urgency about forcing some truth-in-labeling changes has to end.
A lawsuit against five sunscreen manufacturers argues that the product labels are misleading. The sun protection factor, or SPF, is only a measure of the sunburn-inducing and less harmful UVB rays and not those that cause skin cancer, for example. Some products even claim they provide "broad-spectrum UVA/UVB protection," for all types of invisible ultraviolet rays, but that's not usually the case, health organizations say.
That's not good news for beachgoers and anyone working out in the Florida sun.
The FDA ordered sunscreen companies to remove absolute words like "waterproof," "all-day protection" and "sunblock" from their labels in 1999. But the agency - clearly losing sight of its priorities - never enforced these revisions because the corporations wanted to run more tests.
There is a need to move more quickly. The American Cancer Society predicts that of the 1-million skin cancer cases each year, about 62,000 of them will be melanoma and that the disease will claim about 10,700 lives. Misled by the labels, sunscreen users may be assuming they are more well-protected from the sun's harmful rays than they are. And skin cancer cases will continue to rise until the truth is spelled out on the labels.

Skin Cancer Playing Outdoor Sports
One danger with playing outdoor sport at summer time is the risk of skin cancer. It's even worse when your career means you tend to follow the sun. Test cricketer Michael Clarke has discovered this the hard way, revealing he recently has been twice treated for the disease. The good news, though, is doctors have given him the all-clear. Clarke plans to help educate children about the dangers of not slip, slop and slapping. Clarke's Testing time.
